Subject: [PATCH] Make log message in invalid regular expressions more verbose

Make logging of erratic regular expressions more verbose to help
identification and resolving of the configuration issue:

eg.:
old: 24 Dec 18:40:09 - [error] [change:Strip kW] Invalid regex: *kW
new: 24 Dec 18:40:09 - [error] [change:Strip kW] Invalid regular
expression: /*kW/: Nothing to repeat

old: 24 Dec 20:15:57 - [error] [change:Strip kW] Invalid regex: *kW
new: 24 Dec 20:15:57 - [error] [change:Strip kW] Invalid regular
expression: /[kW/: Unterminated character class
